I read the value of an input element which works fine on the laptop. But on a mobile phone (iPhone and Android, Safari and Chrome Browser) it responds with the above error. Do you have any explanation for this?
@Jorg_Beyer unfortunately no, we tried to reproduce it but haven’t had any success. Could you please provide your minimum reproducible example of this issue on a separate page?
I think I found the problem. I call a custom function which calls another custom function. Both functions use the same names for the variables that are passed when they are called.
The renaming of the variables did the trick. Problem solved. This problem occurs only on mobile phones, not at the desktop/laptop browser.
